Different infill in the same part

This answer explains that you can have different infill within the same part. Firstly the implementation in Ultimaker Cura is described, secondly how you can do this in Slic3r. Ultimaker Cura I've ...

How does one use a heat tower?

When you slice an STL of a heat tower, you need to tell the slicer that you need a different temperature at a certain level and maintain that new temperature until another change is requested. The ...

Why do some models appear broken in slicing software?

My understanding is that this occurs when the object is not a true solid. Since an STL holds the triangulation of each face and spline, the slicing engine is not "smart" enough to determine ...

Why is it conventional to set line width > nozzle diameter?

There are several things at play that can make a wider line nice to have: First layer adhesion Due to some filaments having serious struggle to get the first line or layer stuck to the bed, it can be ...

Slicer line width vs. extrusion multiplier for layer adhesion?

Generally speaking, both settings result in the same1: The feed rate of the filament gets adjusted. Either you set a general multiplier, or you demand a wider line which does make it set a higher ...

Why is it conventional to set line width > nozzle diameter?

Shouldn't a 0.4 mm nozzle create a line of plastic 0.4 mm wide Not necessarily. Due to a phenomenon known as die swell extruding plastic through a 0.4 mm nozzle, the line of plastic ...

How to configure Cura to run the Z probe before heating

In Cura (and Slic3r), you can 100% customize what the printer does before printing your actual model through custom start/end g-code. If you navigate to the ...

Why is the bottom of my part not smooth

Your nozzle is too far from your bed. The first layer isn't squished down sufficiently, resulting in these gaps. If your first layer looks like this, you should cancel your print and adjust the bed. ...

Different infill in the same part

I don't particularly recommend the following, but it may be easier than 0scar's answer (which I would recommend implementing if you use Cura). Slice your object twice, once at the lower infill and ...

Extrusion adjustment

SHORT ANSWER You're not supposed to do the single-wall perimeter thickness test to calibrate Simplify3D. That screws up the extrusion volume. The correct volume calibration procedure for S3D is: ...

Cura 2.4 missing "split object into parts"

I don't think this feature was implemented at all with Cura v2.x. As the developers say on the v2.1 release, "Cura has been completely reengineered". Finding proper changelog documentation appears ...

Slic3r: How can I automatically modify the STL filename?

The filename is under the "Print settings" tab. Under output options, you can change the name template. You can use words like: [layer_height] to make the name dynamic. The variable you are looking ...

Slicing problem - Slic3r prusa

It's a nozzle size issue. The model contains a lot of details which is really challenging to print with a 0.4 mm nozzle. A big nozzle is just not able to print such fine details. You should ...

How are infill paths connect to form an efficient path that respect the object's geometry?

The answer to this is pretty much basic algebra: The software tackles the problem by using a set of functions that generate the infill pattern for ALL the build volume, then discard anything outside ...

Does the Creality Ender 3 allow variable layer thickness?

Variable layer height is a setting of the slicer, not an ability of the printer itself. However, the printer must be able to print at such layer heights. Any FDM (Fused deposition modeling ) or FFF (...

Why does Cura insert G0 commands between G1 commands while Slic3r doesn't?

Formally, G0 is a rapid move and G1 is a coordinated move. A G1 will cause the printhead to move in a straight line from the begin to the end position, whereas a G0 allows the printhead to move in any ...
